A pod of 40 bottlenose dolphins were spotted jumping out of the back of the breaking waves that were rolling into the east coast of South Africa. Despite facing waves as big as eight feet, some of the more energetic marine mammals were seen leaping six foot out of the sea.

The dolphins were photographed by Mark van Collier as they made their north up the east coast of South Africa, near Port St Johns. Mark travelled alongside the pod on a boat and was amazed to see so many dolphins ‘surfing’ in unison.

Are you considering a trip to Sea World? Before doing so, take a moment to watch the new full length trailer released by CNN films of Blackfish.

Blackfish is the Sundance decuting film about killer whales in captivity and their propensity of living up to their namesake.

The haunting footage revolves mostly around one whale, Tilikum, responsible for the very public and very horrifying death of a Sea World trainer in 2010.

Are these animals truly killers, or did we make them into killers when we stuck them inside a tank and made them perform for crowds? That seems to be the essential question at the heart of Gabriela Cowperthwaite’s unsettling documentary.

Watch the trailer for Blackfish:

Blackfish opens in limited release July 19. Here’s the official synopsis:

Many of us have experienced the excitement and awe of watching 8,000 pound orcas, or “killer whales,” soar out of the water and fly through the air at sea parks, as if in perfect harmony with their trainers. Yet, in our contemporary lore this mighty black and white mammal is like a two-faced Janus—beloved as a majestic, friendly giant yet infamous for its capacity to kill viciously. Blackfish unravels the complexities of this dichotomy, employing the story of notorious performing whale Tilikum, who—unlike any orca in the wild—has taken the lives of several people while in captivity. So what exactly went wrong?

Shocking, never before seen footage and riveting interviews with trainers and experts manifest the orca’s extraordinary nature, the species’ cruel treatment in captivity over the last four decades and the growing disillusionment of workers who were misled and endangered by the highly profitable sea-park industry. This emotionally wrenching, tautly structured story challenges us to consider our relationship to nature and reveals how little we humans have learned from these highly intelligent and enormously sentient fellow mammals.

In many animal societies, if a member of a group is gravely wounded or born with disabling deformities, that animal becomes an unsustainable burden on the others, and is often left behind at the mercy of predators, hunger and disease.

Not so with killer whales. They are among the few species in the world to look after members of their family who cannot look after themselves. Their patience and compassion for each other surpasses, perhaps, even that of humans

The most recent example of this extraordinary commitment to one another was revealed recently in the UK’s Daily Mail, which ran a story and photo essay of a disabled young male orca off the coast of South Africa. The disabled killer whale that is missing two fins is able to survive in the wild with the help of its family, who hunt food its food. The young killer whale has no dorsal fin or right-side pectoral fin, leaving it unable to hunt for itself.

These disfigurements make it impossible for the whale to hunt alongside his pod. Luckily for him, they are only too willing to hunt for their disabled pod mate.

Underwater photographer Rainer Schimpf came face to face with the pod while the members hunted in waters off Port Elizabeth in South Africa. He said: “Incapable of fast hunting and ambushing prey it has to be dependent on the pod which, one assumes, looks after it very well. It shows these mammals are not really just ruthless killing machines but they also have complex, caring social-structures in which they and care for their own disabled members.”

Of course, the more you learn about the intelligence, compassion and complex social bonds these amazing animals have developed over millions of years of evolution, the idea of keeping them locked up in tanks for human entertainment and profit becomes even more ludicrous.
